Which one do you like it better?
I personal like Revenge better than Greed & Ambition. Heroes/villains can only do so much for greed & ambition because for them their own life is more important. On the other hand, Hs/Vs can do anything for revenge including with unbelievable sacrifices. Their actions are more unpredictable. They sometimes sacrifice their own life, everything they have as long as they can revenge.
